The present invention is to improve the convenience and workability of the painting work to increase the coating quality at the same time the opening and closing operation of the opening and closing parts even if the operator applies a little force to solve this problem.

To this end, according to the present invention is to install the stay operated by the force of the gas shoba to the opening and closing parts of the vehicle, looking at each component in detail as follows.

An upper link bar 10 and a lower link bar 12 having a predetermined length are provided, and the upper link bar 10 and the lower link bar 12 are connected to each other in an adjustable angle.

That is, since the opening angle of the opening and closing parts are different according to the vehicle model, the lower end of the upper link bar 10 and the upper end of the lower link bar 12 are padded with a plate-shaped bracket, and then the angle adjustment rotary pin 14 is used as a rotation pin. Will be connected.

At this time, the upper end of the upper link bar 10 is integrally attached to the first bracket 18 having a structure in which the fitting groove 16 is formed to be fastened to the opening and closing parts of the vehicle, the lower end of the lower link bar 12 A second bracket 20 having a fitting groove 16 is integrally attached to the vehicle body panel (for example, a radiator member in the case of a hood) at a position corresponding to the opening and closing part.

In addition, the first horizontal bar 22 is integrally attached to a predetermined position of the middle portion of the upper link bar 10 (section between the first bracket 18 and the angle adjustment rotary pin 14), The single horizontal bar 22 is in a vertical orthogonal state with the upper link bar 10.

In addition, the second horizontal bar 24 is integrally attached to a predetermined position of the middle portion of the lower link bar 12 (section between the second bracket 20 and the angle adjusting rotation pin 14), The bilateral bar 24 is in a vertical orthogonal state with the lower link bar 12.

Here, a pair of gas bars 26 arranged up and down between the first horizontal bar 22 and the second horizontal bar 24 are installed, and the upper end of the gas bar 26 is the first horizontal bar. The bottom of the bar 22 is fastened by a hinge, the lower end of the second horizontal bar 24 is fastened by a hinge.

Gas bar 26 of the present invention, unlike the known gas bar, that the sealing material (not shown) between the cylinder and the piston of the gas bar is made of a special carbon material to maintain a good sealing state even at high temperature of the coating process It is characteristic in that it is used.

During the painting process of the vehicle, a process such as passing the car body through an oven at a high temperature (300 ° C. or higher) to quench the intermediate coating layer is performed. ˜100 ° C. is a standard of use), which causes shrinkage when passing through a high-temperature oven, resulting in a gas leak inside the gas stove, making it inoperable.

However, the gas shock absorber 26 of the present invention is applied to a carbon special material that can easily withstand the sealing material of the cylinder and the piston even at high temperature, so that the normal operation of the gas shock absorber can be continuously maintained.

In addition, an anti-painting cover (not shown) is covered on the surface of the gas stove 26 so as not to get paint or the like during the painting process, and when water generated during the pretreatment and electrodeposition processes during the painting process gets on the gas stove, Water flow grooves (not shown) are further formed on the surface of the gas shobar so that water can flow down and drain.

On the other hand, the first lever 18 of the upper link bar 10 is formed integrally with the operating lever end 30 extending further upward, the paint worker is upward or downward on the operating lever end 30 When only a slight force is applied in the direction, the opening or closing operation of the opening / closing part is smoothly made as will be described later.
